SPECIFICATION forming part of Letters Patent N 0. 738,480, dated September 8, 1903.

Application filed uly 2, 1902. Serial No. 114,060. (No model.)

To a whom, zit may concern:

Be it known that I, ANTON POLLAK, a subject of the King of Hungary, residing in Budapest, in the Kingdom of Hungary, have invented certain new and useful Improvements in Recording Apparatus, of which the following is a specification.

My invention aims to provide improvements in recording apparatus, and especially in apparatus for photographically recording the movement of a ray of light on a sensitive stripas, for example, the oscillating movement produced by the indicator described in my Patent No. 653,881, dated July 17, 1900. According to my present invention I am enabled to record the movements of such an indicator in lines arranged one under the other and transverse to the direction of movement of the sensitive strip.

My present invention provides various other improvements in detail, as hereinafter specified.

An embodiment of the invention is shown in the accompanying drawings, in which Figure 1 is a schematic view,-partly in elevation and partly in section, of the complete apparatus. Fig. 2 is a section on the line2 2 of Fig. 1. Fig. 3 is a side view of the recording apparatus. Fig. 4: is a side view of the same from the opposite direction. Fig. 5 is a vertical section of the recording apparatus on the line 5 5 of Fig. 7. Fig. (3 is a plan of the recording apparatus. Fig 7 is a front elevation of the same. Fig. 8 is a detail in section on the line 8 8 of Figs. 4: and 6. Fig. 9 is a portion of Fig. 4 with the part 26 shown only in dotted lines.

In the patent of myself and J. Virag, No. 675306, dated June 4:, 1901, there are described means of forming closed characters by rays of light moved in two planes at an angle to each other, the rays being deflected either by two different mirrors acting in succession on the ray or by a single mirror adapted for producing either of the movements or any combination thereof.

In my above-mentioned patent, No. 653, 881,.

I have described an apparatus which I call an indicator, in which a small mirror is given an oscillating movement corresponding to the electrical impulses sent over a line of electric communication. My present recording apparatus is shown in connection with indicator from the original source of light is projected from a moving point, whereby the movements of the ray from the indicator may be recorded in successive lines like an ordinary written page without the interposition of any light-deflecting means between the indicator and the sensitive strip upon which the movement of the ray from the indicator is recorded. Patent No. 675,496, and the one mirror having a double movement, each constitute a particular type of indicator to which the light would be projected from a point moving along in a line to produce aline of closed characters. Preferably the indicator moves the ray of light projected on itby an oscillating movement in a plane producing vertical lines of the characters to be recorded, and the point from which the ray is projected onto the indicator moves in a plane at an angle (approximately a right angle) to the first-mentioned plane, thus arranging the characters in horizontal lines. For securing the movement of the point from which the ray is projected to the indicator I preferably use a cylindrical screen having a spiral slit, in the rear of which is any suitable source of light, direct or indirect. As the cylindrical screen isrotated the point 'or portion of the slit from which light is projected toward the indicator moves in a direction parallel to the axis of the screen. To secure the desired angle between the plane of oscillation of the indicator and the direction of movement of the ray proj ected on the indicator, it is only necessary to arrange the axis of this rotating screen at right angles to the plane of oscillation of the indicator. Preferably a pair of screens are used having slits crossing each other at an oblique angle (one of which screens may be a cylindrical screen, as described) and by a relative movement of which a desired movement of the aperture formed at the point of intersection of the slits is obtained.

For example, the two mirrors of,

My invention also provides important features of novelty besidesthose in the lightprojecting apparatus. An important feature is the combination of a receptacle or dark chamber for the sensitive strip, which is c011- nected to a narrow passage forming a lightchamber, through which the strip is drawn and in its passage through which it is eX- posed to the ray from the indicator. Preferably also an observation-window is provided in the light-chamber, by which the operator can observe the movement of the recording ray of light and observe when a message is finished. Preferably also means are provided for drawing the strip through the slit and for cutting off that portion of a strip which contains a completed message after it has passed through the light-chamber. Preferably also an annunciator is provided to indicate the beginning of a message, and on the operation of the annunciator the record-making mechanism, as well as the strip-feeding mechanism, are automatically set in operation. For convenience I may provide also means for simultaneously rendering the feeding and record-making mechanisms inoperative, and preferably also for simultaneously operating the cutter. Preferably also the stopping of the feeding and record-making operations is accompanied by a simultaneous restoration of the annunciator to its normal position.

Referring now to the drawings, A indicates as a whole the indicator; B, the means for projecting light thereon, and O the feeding mechanism, Figures 1 and 2. The parts A and B taken together constitute a mechanism for making a record upon the strip fed through the feeding mechanism G. dicator shown includes an apparatus 1, similar to a telephone, and a mirror 2, connected to the membrane of the apparatus 1 in such a way as to give a desired movement (preferably an oscillating movement) to the mirror, which movement is to be registered. The source of light may be a stationay incandescent lamp 3, which is within a hollow rotating cylinder at, through the wall of which is a narrow slit 5 in the form of a complete or slightly more than a complete spiral. Preferably I arrange in front of this cylindrical screen another screen in the form of a diaphragm 6, having a slit 7, Fig. 7,therethrough, through which rays of light from a point of the spiral slit in the cylinder are projected to the mirror 2. The combination of the two screens with the slits crossing each other forms at their crossing substantially a single point from which the light is projected. This point for each rotation of the cylinder moves once from right to left, (orin the opposite direction, as desired.) The use of the rotating screen has therefore the same effect as if a source of light were itself moved from left to right or right to left, the area of the source of light being reduced to substantially a single point by the interposed diaphragm 6. The area of the aperture formed at the crossing of the two slits 5 The inand 7, however, may be of any desired magnitude, the mirror 2 beingpreferably concave, so as to focus the light reflected to the recording-strip to substantially a point. The light reflected from the mirrorthat is to say, the point of light which is projected on the photosensitive strip Saccordingly moves from left to right (or in the opposite direction) over the strip. As soon as the cylindrical screen has made a complete rotation the starting-point of the spiral slit is again interposed between the lamp and the mirror and the operation commences anew. Since the sensitive strip has in the meanwhile received a desired movement longitudinally, the next line of the record begins at a determined distance from the previous line. It is preferred to move the recording-strip continuously, and this movement, if the recorded line were formed horizontally, would result in the formation of an oblique line across the strip. In order to rectify this obliquity, the slit 7 of the diaphragm 6 and preferably also the lamp are arranged at a suitable inclination, as shown. The roll of sensitive paper 8 is carried in a receptacle or box 9, which is substantially light-proof and is unrolled and drawn out by means of the rollers 10 and 11, Fig. 5, which are operated by means hereinafter described on the outside of the apparatus. From the receptacle or dark chamber the strip is drawn through a narrow passage, in which it is exposed through the opening 12 to the rays of light from the mirror. This passage is closed at the back by an observation-window 13, formed, preferably, of red glass, through which the movement of the ray of light over the sensitive strip may be observed. Preferably, also, an angular mirror 100 is arranged in position to make observation easier. Below the exposing-passage is a cutter, preferably comprising a pair of shear-blades 14 14, the latter stationary and the former movable, by means of which the sensitive strip upon which a message has been recorded may be cut oif after the completion of the message; The various movable parts of the apparatus may be driven by means of a motor 15, Figs. 1 and 2, connected by a belt to the pulley 16- on the cylinder 4, which in turn is connected by toothed pinions to the means for feeding the sensitive strip, Figs. 6 and 7. The rollers 10 and 11, which accomplish the feeding of the strip, are normally in continuous rotation, but when the apparatus is not in use the rollers are separated from each other such a distance that they do not grip the sensitive strip, so as to unroll the same. This operation is obtained by mounting the roller 11, Fig. 5, in a support 17, which swings about a shaft 18 and is moved and held out of contact with the roller 10 by the weight of the arm 19, which latter moves downward when permitted, as hereinafter explained. Preferably the cutting of the indicator A into the circuit and the bringing together of the rollers 10 and 11 (for the purpose of unrolling the sensitive strip) and preferably also the cutting of the incandescent lamp 3 into the circuit are controlled by an annunciator. This annunciator may receive current from any suitable source 20 and includes a magnet 21 and clapper 22, normally held in the upperpositiou shown in Fig. 4 and arranged to drop when a signal calling the operator is given. The clapper drops on one end of the lever 23, pivoted at 24-, pressing down this end of the lever and pressing upward the other end, upon which is a rod 25, which at its upper end presses against a lever 20 and swings the same upward a short distance about its pivotal point 27. The stop 29, carried on the lever 26, is then raised to free a pawl 28, Figs. 4, 8, and 9, on the lower edge of a slide 32. ithin the casing, Fig. 6, is a spring 31, attached to the free end of the shear-blade 14 and tending to pullthe same inward, which free end bears against a disk or similarly-shaped member 30, connected through the side wall of the casing with the slide 32. Therefore when the slide is released by the lifting of the lever 26 the slide is drawn in an inward direction. The member 30 bears on the under side of the arm 19, so as when drawn inward to lift this armand press the roller 11 against the roller 10. By the same inward movement of the slide the stop 33 operates the electric switch by striking the arm 3%, Figs. (3 and 7, so as to rotate the vertical sh af t,which carries at'its lower end spring terminals 36 and 37, which are thus moved to positions over the fixed terminals 38 and 39 in the switch 35, thus closing the previously-opened circuits, which by any suit able connections (not shown) connects the source of current to the indicator and the lamp and preferably to the other apparatus. The pressing of the rollerll against the roller 10 causes the feeding of the strip, and therefore the entire apparatus is now in operation. As soon as the operator observes through the observation-window 13 that the movement of the mirror 2 has ceased he may stop the entire apparatus by a single movement, simultaneously rendering the feeding and recordmaking mechanism inoperative and preferably also cutting oif the finished portion of the strip. Preferably, also, by this same movementhe restores the annunciator to its original position. For this purpose the slide 32 is provided with ahandle 4:0, by the pulling of which outward the several operations stated are controlled. The stop 41 on the slide 32 engages the arm 8 L of the switch 35 and moves the same outward to a circuit-breaking position, in which the terminals 36 and 37 are off the terminals 38 and and the current to the indicator, lamp, 850., is broken. At the same time the member 30, which is connected to the slide, presses outward, against the action of the spring 31, the blade 1- of the shears against the stationary blade 14, so as to cut off the desired portion of the sensitive strip between them. The arm 19 of the support 17 of the releasing the handle 40 the spring 31 draws the slide inward until the pawl 28 engages the stop 29, which prevents the restarting of the several devices.
